We describe a new species of Discostella from Guiyang based on light and scanning electron microscopic observations,as well as molecular analysis.This species is morphologically distinguished from other species by a relatively smooth and slightly recessed central area with marginal striae of unequal lengths forked near the margin.Marginal fultoportulae and a single rimoportula are situated between every two costae or on the costae.Both morphological characters and the concatenated data of rbc L and SSU rDNA indicate that Discostella guiyangensis is a unique and new species.According to divergence time estimation analysis,Discostella guiyangensis is the oldest species among the Discostella species sequenced currently.In addition,we complement molecular data of Discostella asterocostata and Discostella stelligera. 展开更多

An integrative study based on morphological data and mitochondrial molecular data of all known Nanorana(sensu stricto)species have revealed a new species from the Hengduan Mountains,N.huangi sp.nov.The new species can be distinguished from its congers by its:(1)medium body size,SVL 31.3–40.6 mm in adult males(n=12),39.2–48.1 mm in adult females(n=8);(2)absence of subarticular tubercles on fingers,with supernumerary tubercles below the base of the fingers small but distinct;(3)presence of dark dorsal patches without pale margins,generally creamy yellow ventral body basically,bright yellow ventral limbs;(4)small but prominent tympanum;(5)tibio-tarsal joint that reaches to the tympanum or the shoulder when hindlimbs adpressed forward towards body;(6)head length more than 30%of SVL.In addition,the new species can be separated from all other congeners by uncorrected genetic distances:ranging from 2.8%–7.5%of the mitochondrial 12S rRNA,1.1%–2.1%of the 16S rRNA,and 7.5%–11.5%of the COI. 展开更多

(Lepidoptera: Pyralidae) from Taiwan. From 2009 to 2016, a biology study was conducted on population dynamics and embryonic development. Spring season is the peak of the eclosion of overwintering larvae or pupae. The average longevity of adult was 14.8 ± 6.2 days (N = 174), the average number of eggs laid was 259 ± 3 eggs/moth (N = 2), the hatching rate of eggs was 95.4% (N = 262), and the average hatching time of eggs was 99.6 ± 18.6 hours (N = 68). The average body length of males was 5.64 mm ± 0.91 mm (N = 30), and the average body length of females was 6.28 mm ± 0.84 mm (N = 30). This finding indicates that female snout moths are larger than males (Global R = 0.058, P = 0.012). The snout moth eclosion rate was 16.9 moths/100 pods in the first year (2010/2011, N = 2,224 pods) and 10.9 moths/100 pods in the second year (2014/2015, N = 6,382 pods). The pod borer rate was 31.8% (N = 707) and the seed borer rate was 41.2% (N = 3,628) in the first year, whereas the pod borer rate was 76.2% (N = 6,382) in the second year. 展开更多

The inland saltwater lakes harbor exceptional biodiversity.Here,two new species of solitary sessile peritrich ciliates were isolated from Qinghai Lake,the largest inland saltwater lake in China.Their morphology,ciliature,silverline system,and molecular phylogeny were investigated based on live observation,silver staining,and analysis of the small subunit ribosomal DNA(SSU rDNA).Vorticella paraglobosa sp.n.is characterized mainly by its obconical or elongate bell-shaped zooid,C-shaped macronucleus,single ventrally located contractile vacuole,two-rowed infundibular polykinety 3,and 28-38 silverlines between peristome and aboral tro-chal band and 10-15 between aboral trochal band and scopula.Vorticella cotyliformis sp.n.differs from its congeners mainly by its double-layered peristomial lip,cup-shaped zooid,J-shaped macronucleus,single ventrally positioned contractile vacuole,three-rowed infundibular polykinety 3,and 70-85 silverlines between peristome and aboral trochal band and 21-25 between aboral trochal band and scopula.The SSU rDNA sequences of the two new species were obtained,and the subsequent molecular phylogenetic analysis supported their taxonomic classification. 展开更多

Gastrochilus is an orchid genus containing 73 species of mainly epiphytic on trees or rocks in mountain forests of tropical and subtropical Asia.Previous phylogenetic analyses and morphological assessments have failed to produce a well-resolved phylogeny at the infrageneric level.In the present study,a new infrageneric classification of Gastrochilus is proposed based on thoroughly morphological and phylogenetic analyses based on 52 species.Our phylogenetic analysis divided the genus into six sections including three new sections,G.sect.Pseudodistichi,G.sect.Brachycaules and G.sect.Acinacifolii.We also reinstate G.suavis to the specific rank.Furthermore,two new species,G.armeniacus Jun Y.Zhang,B.Xu&Yue H.Cheng and G.minjiangensis Jun Y.Zhang,B.Xu&Yue H.Cheng,are described and illustrated.A key to six sections of the genus is presented. 展开更多

The new genus Parathrausta gen.n. in the subfamily Spilomelinae (Lepidoptera, Crambidae) is erected based on a series of specimens collected in the Afrotropical region of Saudi Arabia. The new genus is monotypical, with Parathrausta internervalis sp.n. its type species. The adults of the type species, the male genitalia, the female genitalia and the tympanal organs are described and figured. The new genus is recognized as related by characters in the male and female genitalia with genera in the tribes Steniini Guine, 1854 and Nomophilini Kuznetzov & Stekolnikov, 1979, namely with Bradina Lederer, 1863, Perisyntrocha Meyrick, 1894, Diathrausta Lederer, 1863, Diasemiopsis Munroe, 1957, Diasemiodes Munroe, 1957 and with the genera in the Duponchelia Zeller, 1847 group comprising Duponchelia Zeller, 1847, Penestola Mschler, 1890, Tatobotys Butler, 1880 and Hymenoptychis Zeller, 1852. The character states differentiating the new genus from the comparative genera are discussed. Potential autapomorphies of the new genus are listed. The tribal assignment of the new genus to the Nomophilini Kuznetzov & Stekolnikov, 1979 based on morphological characters is discussed. The support of the tribal and cladistic assignment of the new genus as a sister clade to Diathrausta Lederer, 1863 based phylogenetic analyses (NJ, MP and ML) is shown. An unusually strong genetic divergence of the genus in the COI segment of the mt-DNA based on the Tamura-Nei distance measure from the morphologically related genera is recognized and addressed. 展开更多

The Macrophya planata species group is proposed and defined by mesoscutellum very fiat with sharp lateral carina and the dorsal side of some antennomeres white. A new species of the group from Tibet, China is described: Macrophya acutiscutellaris Wei, Li & Heng sp. nov.. The new species is similar to M. pseudoplanata Saini et al., 1996, but differs from the latter in body length 13.5 mm in female; apical third of hind tibia entirely black; antenna 2.5 times as long as head breadth; postoeellar area 1.6 times as broad as long; harpe weakly narrowed toward apex. A key to all known species of Macrophya planata group is provided. Type specimens of this new species are deposited in the Insect Collection of Central South University of Forestry and Technology, Changsha, Hunan, China. 展开更多

A new species of the subfamily Labeoninae, Garra nujiangensis Chen and Yang, sp. nov. is recognized from a secondary branch of Nujiang River (upper Salween) in Zhenkang county, Yunnan province, China. It can be distinguished from other beardless Garra species by the following combination of characters: 12 - 14 circumpedunele scales; 48 - 50 lateral- line scales; a pair of rudimentary rostral barbels present in little individuals; 8 - 9 branched dorsal-fin rays; 5 - 6 scales between dorsal-fin origin and lateral line and 3 - 4 scales between pelvic-fin origin and lateral line; caudal peduncle relatively stouter; length between snout tip to posterior margin of eye longer than body depth at anal fin origin; head length longer than body depth at dorsal fin origin; prepelvic length 50.0% - 53.7% of standard length; pre-anus length 58.9% - 63.9% of standard length; body width 16.7% - 19.6% of standard length; body depth at dorsal fin 19.2% - 22.6% of standard length. The present study also verified that the presence of tiny barbells is a juvenile character in some beardless Garra species, such as G. nujiangensis and G. alticorpora. 展开更多
